[Coordimetric screens. Critique and possible improvements]

Area of Science:

• Ophthalmology
• Visual Science
• Optometry

Background:

• Standard visual screen tests are often square and limited in length.
• Existing square screens present challenges with variable angular values and pattern limitations.

Observation:

• The current square visual screen tests are too short for comprehensive evaluation.
• The square pattern with variable angular values on these screens is disadvantageous.

Findings:

• A novel 2.10 m hexagonal screen with a trigonometric square pattern is proposed.
• This hexagonal screen design allows for correct estimation of visual deficits.
• The proposed screen effectively detects shorter visual anomalies.

Implications:

• This new screen design has the potential to enhance diagnostic accuracy in visual testing.
• It may lead to earlier detection of visual impairments.
• Adoption of hexagonal screens could advance the field of visual assessment and patient care.
